AUTO-LOCK:

-Be it known that I, MIKE F. Kamson,

a citizen of the United States f A.merica,.

residing. at Independence, in the county of Trempealeau and State of Wisoonsm, have invented new and useful Im rovements in Auto-Locks, of which the ollowing is a Specification.

The principal object of the inventionfis to provide means for effectively locking in gears in the transmission mechanism of an auto vehicle. J

. A further object of the invention isto pro-- vide a lock of this nature which may-be readily applied to such lever so that it will perform its function and require only the drilling of a hole in the lever to permit the effective performance of thisfunction.

A still further object seeks the provisionof a lookin device of the character mentioned whic is simple in construction, du-v rable in use and inexpensive to manufacture. Still further and other objects will appear in the following detailed description.

To the exact embodiment to which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual re'-- duction to-practice may suggest, in so'far as such changes or alterations are compatible with the spirit of the annexed claim. In the accompanying drawings:

Figure 1 1s a perspective view showingthe shifting lever of an auto vehicle transmission gears and showing the improved locking device attached thereto.

. Fig. 2 is a sectional view through a portion of the structure shown in F ig; 1.

Fig. 3 is a perspective view of the block against which the locking "pin engages.

Referring to the drawings, there is shown the transmission gearing shifting lever 1 and the base plate 2 through which the lever projects to enter the interior of the car from the transmission case below.

The improved lock. is in the form of a block 3 made preferably substantially square in plan and having the corners removed, as shown at 4, so that there may not be any shar corners which may engage and cut the ban s in the use of the device. At its cen- 1 Speciflcationof Letters Patent.

cross sectional shape of the lever 1. FarcessI6 crossing the eye and extending from one corner 4 to thediagonally opposlte corner.

In applying the device, the handle 7 is removed, whereupon the block is attached to the lever 6 having thelatterpassed through f its eye 5, The block then rests upon the plate 2 after having been placed on'the lever so that the recess 6' isupward. The lever 2 is then drilled transversely to receive .the pin 8, the position of this hole being such that when the lever is in the neutral position the 1 block 3 rests upon the plate 2 and the pin 8- lies in the bottom of the recess 6. The oval shaped rlng 9 which isplaced over the lever locked to the by means of a lock 10, the lock engaging both the egell) of the pin and gaged by the lock' and the lock engaged with the ring. Therefore, the lever 1 cannot be moved, since the block is held tight against the plate 2 and resists any force tending to shift the lever angularly from its neutral position.

To unlock the device, the lock 10 is disen} gaged, whereupon the pin 8 may be withdrawn from the lever and theblo ck 3 raised, so that the pin may be inserted beneath the a position that the necessary movement may be imparted to the lever to effect the desired shifting of the gears in the transmission mechanism.

From the foregoing description and the accompanying drawings it is believed a clear enough understanding of the invention will I which the said lever passes, the block resting upon the floor plate and having on its upper Patented Sept. 16, 1919. A Application me m 2a, 1918. SerialNo. 246,344.

ther thanthe eye 5, the block is'provided on one face with the diagonally disposed re-' '1 after the ,block is attached thereon is'then block. Thereafter the block is held in such 75 the ring 9. It will thus. e observed that the pin cannot be withdrawn aslong-as it is en-" face a recess extending clear across the face pin having an eye formed at one end, an and across the eye, the lever having a transoval shaped mug in surrounding relation to verse hole formed therein so that when the the lever, and a lock securing the ring to the 10 lever is in neutral position one side thereof eye of the pin, all for the useful purpose Will register with the Wall of the recess, a specified. pin inserted through the hole in the lever In testimony whereof I afiix my signature. and lying in the said recess in the block, the MIKE F. KARASCH.
